WINDING 0R SPOOL-ING- MACHINE.

Specification of Letters Patent.

Patented Nov. 25, 1919.

Application filed May 23, 1919. Serial No. 299,207.

To all witom it may concern:

Be it known that I, Fnnonnio W. EASTON,

a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Winding or Spooling Machines, of which the following is a specification;

This invention relates to certain new and useful improvements in a winding or spooling machine, and more particularly to the head construction, the principal object being to provide means for varying the degree of friction exerted or placed upon the yarn.

A further aim and important object resides in the self-threading feature by means of which the yarn is guided into the friction applying device in an automatic manner.

The invention consists in the features of construction and the arrangements and combinations of parts hereinafter described and claimed, reference being had to the accompanying drawing wherein Figure 1 is a fragmental view showing my invention applied to and embodied in a winding or spooling machine.

Fig. 2 is a front elevation thereof, looking from the right in Fig. 1.

Fig. 3 is a side elevation looking from the opposite side to that disclosed in Fig. 1.

Fig. 4 is a top plan view with a portion of the superposed friction device broken away.

Referring more in detail to the disclosures, the yarn 1 is supplied from a hank, bobbin, or other container (not shown) and passes up over the head 2 of a winding or spooling machine from whence it is directed through a guide eye 3 to the receiving bobbin 4. The guide eye is carried by a trans verse rod or bar 5 which has an up and down movement imparted thereto for laying the yarn properly on the bobbin or spool 4.

Secured on the forward side of the head 2, at a downward inclination, is a vertical series of friction or drag wires 6, the series depicted involving only three such wires which have their outer end portions alternately deflected in opposite lateral direc-' tions so that the intermediate wire will turn to one side and the uppermost and lowermost wires turn to the opposite side. This arrangement of deflections affords a wide mouth to receive the yarn and guide the same between the parallel inner portions of the wlres. Owing to the angular disposition of the head the yarn will be drawn into the 'posrtioninchcated in Fig. 1 down onto the smooth surface of the head, passing back and forth between the wires.- The degree of friction of the wires on the yarn is readily governed'by passing the same back and forth between more or less of the wires. Thus, the yarn may be woven merely between two of the wires, or any number depending upon the number composing the series. I

Secured to the top or upper face of the head, as by a bolt 7, is a bracket structure 8 substantially of triangle form, having the hypotenuse or inclined edge 9 overhanging the head together with the horizontal U- shaped arm 1O which is supported slightly above the head to receive the yarn therealso with a friction applying device in the form of a washer or disk-like weight 11 which is freely held in position to drag on the underpassing yarn by means of a post 12 carried by the bracket and passing through the central aperture of the weight. Because of the relative sizes between the post and the weight aperture, the weight or washer has limited and unguided lateral movement. as well as vertical play. The washer may thus readily tilt to permit the introduction of the yarn therebeneath and to facilitate this operation the lower peripheral edge portion of the washer is beveled inwardly, as depicted at 13.

This washer weight provides a uniform drag or friction on the yarn, any additional friction being supplied by passing the thread selectively between the friction wires. The

yarn is dropped between the selected con beneath the washer weight because of the straight pull thereon.

The thread will thereby be maintained under the proper tension for winding, the degree of tension being variable by means of the wires 6. The construction is simple and involves but few parts which are economically constructed and easily repaired.

' By reason of the vertical bolt 7, which functions as a spindle, the bracket may be swung to and from operative position so that the operator may easily gain access to the thread therebeneath. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination with the head of a winding machine, a substantially triangular bracket on the head, a bolt passed through the vertical leg of the bracket and secured to the head, a post depending from the hypotenuse of the bracket, a weight mounted on the post and a horizontal U-shaped arm at the base ofthe bracket extending about the weight and arranged slightly above the head to receive the yarn therebeneath, onev side of the arm being connected to the hypotenuse and the opposite side to the vertical leg theyarn passingbetween the head and weight and the latter pressing the yarn against the head to effect tensioning of the yarn. I

2. In combination with the head of a winding machine, a substantially triangular bracket on the head, a horizontal U-shaped arm at the-base of the bracket one side of which 1s connected to the lower end of the by.

I potenuse of the bracket, said arm being arranged above the head to receive the yarn therebeneath, and a weight movably carried by the hypotenuse of the bracket and depending therefrom, I the yarn passing between the head and weight and the latter pressing the yarn against the head to effect tensioning of the yarn.

3. In combination with the head of a Winding machine, a substantially triangular bracket on the head, a horizontal arm at the base of the bracket and arranged above the head to receive the yarn therebeneath, a post depending from the hypotenuse, and a weight loosely mounted on the postand'-ar ranged to one side of the arm, the yarn passing between the head andweight and the latter pressin the yarn against the head to eftectten'sioni'ng of the yarn.

4. In combination with a head of a winding machine, a substantially triangular bracket on the head, a post depending from FREDERIO w. EASTON. Witnesses: l
